|ADMIN_PLACE_ID||Permanent administrative place ID. An administrative place is a government defined entity like a city, region, county, state or country. This ID can be used to identify the census data attached to a administrative area.|
|ZONE_ID||Permanent identifier of a Zone to which the census data is applicable.|
|CENSUS_ID||Census ID defines a unique identifier that indicates that the data is referencing Census data. This ID is not permanent over quarters.|
|CENSUS_TYPE||Defines the Census Type that is applicable to the Admin Place or Zone.|
Census Type = 1 - Census Code defines that the Census data is referencing the Census Codes, previously known as the Federal Information Processing Standard (FIPS) code. Census Codes are currently published as the Admin Place government code.
Census Type = 2 - Census Class Code defines the census classification of a place. An example would be:
C1: Identifies an active incorporated place that is not also recognized as an Alaska Native Village statistical area, and does not also serve as a primary county division; that is, it is included in and is part of a primary county division. For example, the city of Hammond, Indiana is within and part of North township; the city of Austin, Texas is within and part of several census county divisions in several counties; Hammond and Austin are coded C1.
Census Type = 3 - GNIS Feature ID defines that the Census data is referencing the Geographic Names Information System (GNIS) Feature ID. GNIS Feature IDs are similar to Census Codes. GNIS includes geographic names for all known places, features, and areas in the United States that are identified by a proper name. Census Codes defined for level 4 Administrative Areas and Zones are being phased out by the U.S. government and replaced by GNIS Feature IDs. However, GNIS Feature IDs are an addition to and not a replacement of Census Codes. New places only get a GNIS Feature ID assigned. For new places the government code publishes the GNIS feature ID.
Census Type = 4 - CBSA Metropolitan Statistical Area defines that the Census data is referencing the Core Based Statistical Area (CBSA). CBSA is a collective term for both metro and micro areas. A metro area contains a core urban area of 50,000 or more population, and a micro area contains an urban core of at least 10,000 (but less then 50,000) population. Each metro or micro area consists of one or more counties and includes the counties containing the core urban area, as well as any adjacent counties that have a high degree of social and economic integration with the urban core (as measured by commuting to work).
Census Type = 5 - CBSA Micropolitan Statistical Area. See definition above.
Census Type = 6 - NECTA Metropolitan Statistical Area defines a set of geographic areas that are defined using cities and towns in the six New England states. The New England City and Town Areas (NECTAs) are defined using the same criteria as Metropolitan and Micropolitan Statistical Areas and are identified as either Metropolitan or Micropolitan. A metro area contains a core urban area of 50,000 or more population, and a micro area contains an urban core of at least 10,000 (but less then 50,000) population.
Census Type = 7 - NECTA Micropolitan Statistical Area. See definition above.
Census Type = 8 - Metropolitan Division defines that the Census data is referring to a county or group of closely tied contiguous counties that serve as a distinct employment region within a metropolitan statistical area that has a population core of at least 2.5 million. While a Metropolitan Division is a subdivision of a larger metropolitan statistical area, if often functions as a distinct social, economic, and cultural area within a larger region.
Census Type = 9 - NECTA Division defines NECTAs (see definition above) containing a single core with a population of at least 2.5 million that are subdivided to form smaller groupings of cities and towns referred to as NECTA Divisions.
|CENSUS_VALUE||Defines the Census Value applicable to the Admin Place or Zone. The value corresponds to the Census Type.|
Census Value for Census Type = 1 publishes the Census Code. Census Codes are used as the government codes currently published for Admin Places in the U.S. This data is also published as Census data for completeness.
Census Value for Census Type = 2 publishes the Census Class Code corresponding to the FIPS 55-3 standard. Census Class Codes are alphanumeric and defined at http://geonames.usgs.gov/pls/gnispublic. Census Class Codes are published only for level 3 and 4 Administrative Areas and Zones.
Census Value for Census Type = 3 publishes the GNIS Feature ID. Census Codes (Census Type = 1) and GNIS Feature IDs (Census Type = 3) are published for Administrative Areas (Admin Level 1-4 in the U.S.) and all Zones with official government codes.
Census Value for Census Type = 4 publishes the CBSA code for Metropolitan Statistical Areas. CBSA codes are published for one or more Counties where applicable.
Census Value for Census Type = 5 publishes the CBSA code for Micropolitan Statistical Areas. CBSA codes are published for one or more Counties where applicable. CBSA Metropolitan or Micropolitan areas (Census Type = 4 or 5) can span multiple Counties. There is one CBSA that defines a partial county. St. Louis, MO-IL Metropolitan Statistical Area only includes the Sullivan City part of Crawford County, MO. For this specific case the complete Crawford County are published with the CBSA code (41180) for St. Louis, MO-IL.
Census Value for Census Type = 6 publishes the NECTA code for Metropolitan Statistical Areas. NECTAs are published for one or more cities or towns where applicable.
Census Value for Census Type = 7 publishes the NECTA code for Micropolitan Statistical Areas. NECTAs are published for one or more cities or towns where applicable.
Census Value for Census Type = 8 publishes the Metropolitan Division Code.
Census Value for Census Type = 9 publishes the NECTA Division code.
|LANGUAGE_CODE||Language Code of the Census Name. NULLABLE|
|CENSUS_NAME||Identifies the Census Name. NULLABLE. Census Name can be used to identify the name of the CBSA (metropolitan or micropolitan), NECTA (metropolitan or micropolitan), Metropolitan Division, or NECTA Division.|
Census Names are published for the following areas: CBSA Metropolitan Statistical Area, CBSA Micropolitan Statistical Area, NECTA Metropolitan Statistical Area, NECTA Micropolitan Statistical Area, Metropolitan Division, NECTA Division.
Census Names are referred to as 'Title' in the Census Data.
For CBSA and NECTA Metropolitan and Micropolitan Statistical Areas the Name does not include 'Metropolitan Statistical Area' or 'Micropolitan Statistical Area'.
